Study on Magnetic-abrasive Finishing (3rd Report)

Finishing Characteristics of Non-ferromagnetic Substances

Abstract

This paper describes experimental results on how machining conditions, such as magnetic pole shape, magnetic flux density, work speed, vibrating frequency, vibrating amplitude, working clearance, mean diameter of magnetic abrasives, etc., influence the finishing characteristics of non-ferromagnetic substances. From the results, it has been determined that the finishing characteristics are equal qualitatively, but are different quantitatively compared to those of ferromagnetic substances, and the machining efficiency is considerably lower because of both the magnetic field distribution and its field strength in the working zone. Furthermore, it has been clarified that a magnetic abrasive finishing process has the finishing capability of a ceramic bar.
